I love the web audio API. I've been making a game where the theme is "I don't do art" so my assets are CSS, emojis, and manually made sounds using frequency and sinewaves and such. The one lesson I learned the hard way is that if you run a full-volume sine wave long enough you can permanently destroy your laptop speakers.

Reminds me of DOS terminal games like Rogue and ZZT which used ASCII characters to draw everything. I hope you post it once it's ready

Indeed it's a dungeon crawler.

Don't hold your breath. It'll be rudimentary. I'm making it for my own joy and learning, but will probably publish it by EOY.

Minutes. I never repeated the experiment. Maybe my laptop was a dud or something.

If you have not yet seen this site, please free a couple of hours and browse through archives, it's the best educational material I have ever seen! https://ciechanow.ski/archives/

Any idea what framework (if any) this is written in?

Make sure your alerts aren’t muted. I’m on an iPad and I had to check the widget in Control Center to get sound, but then it worked fine.

I still don’t understand why this mutes functionality like this page’s, but not web video or audio players or the like in web pages.

+1 for the recommendation for "The Scientist and Engineer's Guide to Digital Signal Processing" by Steven W. Smith. I spoke to Steven many years ago about his putting all of the book PDFs online for free and since then have recommended at least 5 university libraries to buy it because the students could get free copies of a great book that can be referenced in the library.

FWIW the The Scientist and Engineer's Guide doesn't actually cover a lot on sound. It starts in a particular DSP way with frequency domain definitions and convolution - and I actually think Steven's background is in medial imaging, though I could be mistaken.
